> I think the example for SAMPLE is wrong
> In this example, a scalar expression is used (it will sample approximately
> 1000 records from the input).
> a = load 'a.txt';
> b = group a all;
> c = foreach b generate COUNT(a) as num_rows;
> e = sample d 1000/num_rows;
> There is no relation d and I get a "Projected field [num_rows] does not exist
> in schema" error, I think it need to be
> e = sample a 1000/c.numrows
